This adapter allows feeding the GBB magazine of the VFC FAL / OSW with a High-Cap magazine. I used a "Dboys SCAR-H Mk17 500rds Magazine".

 There is quite a lot of filing and dremmeling needed. Therefore I only recommend it for experienced Airsoft-Modders. :) 

Additionally there is a magazine top cover for adding 7.62mm/.308 decoration ammo. 

And further there is covers for the front and back, to mimic a clamping shell.

In the pictures still the HPA adapter is missing. It will be added with a threaded adapter (e.g. M5) directly into the rear of the VFC GBB magazine. 

More information about the complete rebuild can be found here: https://www.airsoft-verzeichnis.de/index.php?status=forum&forennummer=0000000000&sp=1&threadnummer=0000708682&seite=1

This design was quite the effort. If you enjoy this design and it gives you benefit in your life, consider a tiny contribution to my Paypal. It would be well appreciated. :) --> Paypal.me/KorbiMuster
